SANITARY DO'UCl-IE.

Application filed. July 10,

and useful l mprov'lncnts in Sanitary Doucnes, oi which the following isa specilication.

This invention relates to a sanitary douche, and has tor its obiect toproduce an instrument for applyi a lluid or solution tor washing ormedicinal purposes to internal 1 ns oi the body. A further object is tosuch an instrument for draining one such organs by a separate passageand t ereby insuring the instant re moval of the contau'iinated fluidsolution and hence the effectiveness of the treatment.

lVith these general objects in view the invention consists incer;..ainnovel and useful lOtltlll'OS of construction and organizationof par as hereinafter described and claimed; and in order that it may befully understood reference is to be had tothe accompanying drawing, inwhich:

Figure 1, is a perspective view of a douche embodying the invention inthe preferred 'torm.

i". 2, is a view partly in side elevation "ly in central section of thedouche.

a cross section taken on the line Hllll or Fig. 2.

4;, is iraginental view or a modified torni the instrument.

In the said drawing, 1 indicates atube provided at its front end with anozzle comprising a tubular head 2 of slightly larger diameter than andscrewed upon tube 1, and a deflector 3 having a hollow threaded stern lscrewed into the head, the bore of the latter being enlarged at itsfront end to provide a chamber 5 and a flared end (5. The inner side ofthe deflector is beveled at 7 to substantially parallel the flared end 6oi? the head, and the stern l; is provided with an external enlargement8 to fit against the base of the enlargement 5 of the bore of the headand thereby insure the production of a slight space between the beveledextremity of the head and the beveled rear side of the deflector. Thesaid stem between the deflector and the enlargement 8 is provided withone or more apertures 9 through which water or a solution entering thetubular stem escapes from the nozzle and is caused by the beveled end 6of the head and the Specification. of Letters Patent.

juxtaposed deflector, to escape in the form of a thin cone-shaped sheet.

Secured upon the rear end of the tube 1 is a coupling 10 for a flexiblehose ll tor supplying water under pressure from any suitable sourco,such, for example, as a hot water bag.

12 is a tubular sheath of substantially greater diameter than andfitting concentrically around tube 1, the iront end oi the sheathpreferably constituting a slightly enlarged and forwardly taperingdilator 121 so disposed w'th relation to the nozzle, that the dischargeof water or solution trein the latter shall impinge against the innerside 01 said dilator within its flared front end or mouth. 13.

he dilator is provided internally with a wardly facing shoulder 14-iorming a for a spider. fitting on the tube 1 a. r engaged by the rearond ot the nozzle thereof. w

16 is a frustum shaped cap fitting with a water-tight joint on the rearend of the sheath and on the tube 1, the joint of the latter being madewater-tight by the interposition of a gasket 17. The cap is providedwith. a drain nipple 18 having a spherical head "for convenientattachment with the end of a drain tube leading to a suitablereceptacle, not shown. I

To use this douche it is inserted in the organ to be cleansed ormedicinally treated and distends the same, the tissues or membranesbeing therefore smoothed out in eti ect, so that their entire surfaceadjacent the dilator are accessible to water or solution discharge fromthe nozzle. As the instrument is advanced into the organ the entireinner surface thereof is gradually distended or unfolded and broughtunder the force of the spray, the spraying action continuing as theinstrument is withdrawn so that the organ for the length of the insortedpart of the instrument, receives a second treatment.

During the operation described, the used water or solution escapes in acontinuous stream through the sheath and thence from the cap thereof andinto a suitable recepthe features organ and the instrument to bethoroughly drained.

Vfith the type of instrument shown by Fig. 4, the operation is the sameexcept that the dilator 21 makes no provision for drain- The instrumenttherefore must be withdrawn after each charge of liquid passes throughit to This device will operate effectively but is not as sanitary orconvenient in use as the construction embodied in Figs. 1 to 3inelusive.

From the above description it will be apparent that I have produced adevice of the character described which possesses all of pointed out asdesirable, and I wish it to be understood that while I have describedand claimed the preferred embodiment of the same I reserve the right tomake all changes properly falling within the spirit and scope of theappended claims and the principle of construction involved.

I claim:

1. A douche comprising a tube having a nozzle for discharging a conicalsheet of liquid forwardly and outwardly, ahose for supplying liquid tothe tube, and a sheath fitting over and spaced from and adapted toreceive and direct the discharge from the tube and to also receive anddrain oif the contaminated liquid.

2. A douche comprising. a tube having a nozzle at its front end, a hosecoupled to permit of natural drainage.

the rear end of the tube, a sheath fitting around and spaced from andprojecting beyond the front end and terminating short of the rear end ofthe tube, and provided near its front end with an internal forwardlyfacing shoulder, a spider centralizing the tube and sheath and fittingbetween and against the said shoulderof the latter and the nozzle, a capfitting on the tube and closing the rear end of the sheath and providedwith a drain opening, and means for sealing the rear end of the caparound the tube.

3. In a douche, a tube provided with a nozzle comprising a head having alongitudinal bore enlarged at its front end and flaring at its frontextremity, and a deflector provided with a stem fitting in the bore ofthe head and with a shoulder e11 gaging the bottom of the enlarged partof the bore to space the deflector from the front extremity of the head;said stem having a. chamber open at its rear end and a dischargeaperture connecting said chamber with the enlarged part of the bore ofthe head, in combination with a sheath fitting around and spaced fromthe tube and provided at its front end with a flaring mouth, a capclosing the rear end of the sheath, and a drain nipple connected to saidcap.

In testimony whereof I affix my signature.
